Since I aquired an Losmandy G11 mount without any goto provision I decided to create my own solution. I was a bit reluctant to use a Gemini, mainly because of the cost, but also due to the reliability since the servo motors are somewhat prone to failure. I also like to have complete control over the software/firmware so that no "show stopper" issues will ever be a problem for me. Looking around the 'net I saw other goto systems that seemed capable, but either they had needlessly complex hardware or were commercial systems that cost about twice what they should.
OnStep is a computerized goto system, usually for stepper motor equipped mounts though any step/dir interface motor driver (including servo) should work. It was designed, from the beginning, as a more or less general purpose system and provisions were made in the firmware to allow for use on a variety of mounts including Equatorial and Alt/Az (GEM, Fork, Dobsonian, etc.) It uses an LX200 like computer command set with a few extensions to suit hand controller-less operation.
There's a telescope hand controller App for Android (free in the Google Play Store,) an option to control through a website (Smart Web Server,) and a dedicated physical hand controller (Smart Hand Controller.) Or, on a PC there's ASCOM and INDI drivers for control. These options allow you to setup and control OnStep using a wide range of software including my Sky Planetarium, Cartes du Ciel, Stellarium, SkySafari, KStars, PHD2, etc. You can see most of the control possibilities in the diagram below:
Also, please visit my StellarJourney.comsite for updates, links toOnStep resources, my other astronomy software, or to see someImages taken with the assistance of my OnStep operated mounts.
If you find OnStep useful and would like to show your appreciation and support please consider making asmall monetary donation. This keeps me motivated and helps cover expenses associated with my projects.
Wrong title.
If you mean on the Blue Pill PCB, then yes, STM32 compatible microcontrollers will work.
It has to be 128K of flash memory.
A better alternative is the RobotDyn F303CC module.

Hello, i am just starting a project based on ramps 1.4 and eq1, i wonder the following: eq2 like eq1 can’t make a 360degrees turn on it’s DEC axis, it has just a few degrees of turn on eyther

Good to know, i'd like to test this module
On the paper it is written that the Neo6 can get a fix after 18 seconds, i tested this module indoor and outdoor and was not disappointed, around 30

Hi Howard,
I tried 2.7.4 and immediately got the same error after flashing. I re-flashed the device a few times with different libraries and got the same issue in almost every attempt (just one

I tested the AGM336H GPS module with OnStep on a FYSETC S6, and can confirm that it works.
How is this module different from the more widely used NEO 7M ones?
It is very small (15.7 x 13.1 mm), works

Based on the many contacts I've had with OnStep builders a majority of conversions have been performed on GP copies. So there are hundreds of people here who have experience they can share. Don't be

Like I said, it's been a while... guess I skipped that. Regardless, you have set AXISn_ENC_DIFF_LIMIT_FROM so OnStep can't sync (any large amount) to the encoders. The only difference is that the

Hi Friends.
I'm using a MAxEsp 3.03 board and I would like to try Periodic Error Correction in my old EQ5.
Could someone tell me which board pin should I use for ?
Is it possible to connect it

If it's got a large pin that ra attached to, like the meade 6600, I can upload files for RA at least (my dec was diy). (Thought I had, but can't find it on thingiverse.) I think the mount, a licensed

Nice!
In my case, the stepper motor is raised by 3-4mm. Its upper surface is aligned with the cover of this space. The lower compartment allows the motor wires to go on this side, to the connector.
